Abstract (en)
[origin: CA2967098A1] The invention relates to a first method for updating firmware of a computer system, which is embedded in a technical device, wherein the technical device has a volatile memory module, such as a RAM memory, wherein the technical device has a non-volatile memory module, such as a flash memory, in which a firmware update package is stored, wherein the firmware update package contains individual files and associated first checksums, wherein the method runs through the following steps in the specified sequence: a restart (G), a subsequent booting of the computer system (H), and checking if an indicator file exists in the non-volatile memory module (I). The invention relates to a second method for updating firmware of the computer system, which is embedded in a technical device, wherein the method runs through the following steps in the specified sequence: a restart (G), a subsequent booting of the computer system (H), and a check as to whether an indicator file exists in the non-volatile memory module (I).
